262 Analysis of the Factors Contributing to Unplanned Admissions of Surgical Day Cases

Introduction Day surgery has many benefits including a reduction in waiting lists, cancellations, hospital acquired infections and need for inpatient beds. It is also highly cost effective. The aim of this study is to identify which factors lead to the unanticipated admission of day cases, in order to adjust future patient selection, and retain efficiency Method A list of day cases that took place in 2017 was obtained from the HIPE department in St. Luke’s General Hospital. Day case patients who required admission were retrospectively analysed with the use of patient charts. Patient factors such as age, gender and co morbidities were recorded. The root cause of admission was identified, and the data collated. Results 457-day cases took place during 2017. 35/457 patients were admitted postoperatively (admission rate of 7.8%). The majority of patients were admitted post cholecystectomy (22) and incisional hernia repair (8). Surgical factors were responsible for almost all admissions. Conclusions Surgical factors/complications are not always predictable, but a thorough review of a patient’s background history and imaging can lead to the identification of patients, who should be directed away from day surgery, minimising the need for unexpected admissions, and maximising the efficiency of the unit.

Unanticipated Admission Following Outpatient Laparoscopic Cholecystectomy: Identifying Opportunities for Improvement

Background Unanticipated admissions are a burden to the health care system. Over 400 000 outpatient laparoscopic cholecystectomies (LCs) are performed annually in the United States. The aim of this study is to identify causes of unanticipated admissions and modifiable risk factors. Methods Patients undergoing elective outpatient LCs were identified from the 2013-2015 American College of Surgeons National Surgical Quality Improvement Program database. Results A total of 69 376 patients underwent outpatient LC or LC+ intraoperative cholangiogram (IOC); 2027 (2.9%) were admitted after a median of 5 days (interquartile range 3-8). Admission rates varied by preoperative indications: pancreatitis (4.9%), gallstones with obstruction (3.9%), cholecystitis (3.0%), and gallstones without obstruction (2.6%) ( P = .003). The most frequent causes were infection, retained stones, and other GI complications. Patients admitted for infection or cardiopulmonary complications were older with higher American Society of Anesthesiologists (ASA) ( P < .01), while patients with pain and retained stones were younger with lower ASA ( P < .01). Patients who underwent LC+IOC had a lower admission rate due to retained stones (.17% vs. .31% LC, P = .006). Conclusions Unanticipated admissions following outpatient LC occur infrequently for diverse reasons usually within the first week after surgery. Associated factors are patient and disease related and not at all modifiable. In selected patients, increased IOC use may decrease admissions from retained stones.

Unanticipated Admission Following Outpatient Ligament Reconstruction and Tendon Interposition: An Analysis of 3966 Cases

Background: Hand surgeons in the United States commonly perform ligament reconstruction and tendon interposition (LRTI) to address debilitating thumb carpometacarpal arthritis. The objective of this investigation was to examine the characteristics that place patients at risk for unanticipated inpatient admission after a planned outpatient LRTI. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) datasets from years 2009 to 2016 were used to identify patients with a primary Current Procedural Terminology code for LRTI (25445, 25447). Only outpatient, nonemergent, and elective procedures were considered. Univariable and multivariable regression were used to determine risk factors and postoperative complications associated with increased likelihood of unanticipated admission, defined as length of initial hospital stay greater than 0 days. Statistical significance was set at P < .05. Results: Of 3966 patients who underwent outpatient LRTI, 134 (3.4%) had unplanned admission. On multivariable regression, age ≥ 65 years (odds ratio [OR] = 1.50), white race (OR = 4.44), and chronic steroid use (OR = 2.42) were significant predictors of unplanned admission. History of smoking, obesity, hypertension, diabetes, American Society of Anesthesiologists classification, and anesthesia method were not associated with admission. Patients who had unplanned admission had increased rate of reoperation (2.5% vs 0.3%) compared with nonadmitted patients. There was no difference in rate of postoperative infection, deep vein thrombosis, wound dehiscence, or 30-day mortality. Conclusions: Age ≥ 65 years, chronic steroid use, and white race were significant predictors of unplanned admission following LRTI. Identifying patients with these characteristics will be critical in risk adjusting the anticipated cost of the episode of care in outpatient LRTI.
